6. D modeling#
6.1. Characteristics of modeling#
The D modeling uses the equivalent linear model implemented under Code_Aster in Macro-command DEFI_SOL_EQUI [U4.90.21] with an outlying rock loading and a plane wave approach by considering a 1D — 3 components hypothesis. Modeling D adopts the boundary conditions and loading defined in the reference problem.
6.2. Tested sizes and results#
The results of the C modeling are taken for reference at two levels of the soil column, points B (inside layer 4) and E (inside layer 5).
